ZBAR BAR CODE READER
====================

ZBar Bar Code Reader is an open source software suite for reading bar codes
from various sources, such as video streams, image files and raw intensity
sensors. It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39,
Codabar, Interleaved 2 of 5 and QR Code.  Included with the library are basic

bindings are included for C, C++, Python and Perl as well as GUI widgets for
Qt, GTK and PyGTK.
